A Study on the On-Line Monitoring and Diagnostic System of Distribution Transformers

배전용 변압기의 온라인 감시 및 진단 시스템에 관한 연구

This paper suggests the system which monitors and diagnoses the distribution transformers. Moreover, this paper has established the system for the multi diagnoses by all the informations. Through the proven oil sensor, the oil temperature, capacitance and $tan{\delta}$ could be measured throughly, and followed by these informations, detected problems of the distribution transformers, using wireless data communication, could directly reported to the main host. For this, the proposed system is divided into sensor part and controller part. To prove the usefulness of the system, the paper compared and analyzed the system with the existing one, and after studying the correlation of the both, the result proved its goodness.
